Correlation of serum CX3CL1 level and the disease activity of polymyositis and dermatomyositis. Correlations of the level of CX3CL1 with (A) serum creatinine kinase (CK) level (n = 29), (B) manual muscle testing (MMT) score (n = 18) in patients with polymyositis (PM) and patients with dermatomyositis (DM), and (C) the alveolar-arterial oxygen pressure difference (AaDO2) (n = 19) in patients with PM and with DM complicated by ILD. Each point represents an individual sample.
